This article will be interesting to masters who often work with a grinder.
In it, the author of the YouTube channel will tell you how to make a nozzle - an emphasis for the grinder, with which you can very easily cut sheet materials.
Materials
- Steel corners 35X35X3 and 25X25X3 mm
- Steel profile pipe 40X40 mm
- M8 bolts and washers
- Spray paint.
Instruments, used by the author.
- Welding machine
- Bulgarian, cutting wheels
- Sharpening machine or flap disc
- Drilling machine
- Vise
- Clamps, wrenches
- Kern, marking pencil
- Corner, roulette.
Manufacturing process.
So, first of all, Ivan marks the corner 35X35 mm with a wall thickness of 3 mm, length 120 mm. This will be the focus itself. It is advisable to check the source material for an angle accuracy of 90 degrees.
He cuts a corner with a grinder, then marks a corner 25X25, also to a length of 120 mm.
These will be guides for attaching to the angle grinder.
Cut the two remaining workpieces, clean all sharp edges on the grinder.
So all the elements for homemade are ready.
The edge of the 25th corner marks at an angle of 45 degrees.
Pulling two blanks from the 25th corner with a clamp, cuts them off, also cuts off the sharp corners.
This is the form of the blanks.
In order to drill them symmetrically, Ivan grabs them with welding from two sides. Then he tries them on to the grinder and applies marking. Kern marks the exact spot for drilling.
On a drilling machine makes a through hole with a diameter of 8 mm. Then it cuts off the welding points, and separates the workpieces.
Now the wizard has all the elements prepared for assembly.
Attaches the guide angles to the gearbox of the grinder, usually these are M8 bolts, but for large tools it is the M10 bolt.
Steel corners are attached to the base of the grinder a little at an angle, this is due to such a design of the gearbox.
Attaches the assembled structure to the stop corner, grips the first guide by welding.Then, having checked the design parameters with the help of a corner and a caliper, he grabs the second.
Now you can thoroughly boil the seams.
The nozzle is ready, Ivan paints it with spray paint. The sides of the thrust corner can not be painted, it will still be scratched on the metal.
Fixes the nozzle on the grinder, checks the perpendicularity of the disk and stop.
Having marked out a steel sheet (3 mm thick), gently presses it to the table with a 40X40 mm profile pipe and clamps. Then tries on device.
For accurate marking, it checks the distance from the disk to the edge of the stop, it is 120 mm. Then exposes the same distance between the edge of the profile pipe and the markings on the sheet. Clamps clamps completely.
Now, pressing the stop angle to the guide, makes an incision. Pay attention to the direction of rotation of the disc and the movement of the grinder. With this method of cutting, the disc will almost never jam, and it will last longer.
Checking the workpiece with a corner. Everything is fine, the cut was smooth and of high quality, and the angle of 90 degrees was observed.
The most important thing is the processing speed and the accuracy of the results.
Here is a device turned out by Ivan.
Thanks to the author for an interesting device for the grinder, it should facilitate the work of many masters!
Good luck to everyone, good mood and creative ideas!
